Unified Modeling Language (UML) Class Diagramming is the commonly accepted mechanism used to describe relationships between software components. In addition, it is an essential educational tool that is used to convey the structure of software and the patterns of software design to students. Unfortunately, UML is a visual-only mechanism and…

The purpose of this qualitative case study was to describe the strategies teachers chose to successfully differentiate for high achieving upper elementary mathematics students. The context of the study was mixed ability classes in international schools. The study used Vygotsky's sociocultural learning theory as a theoretical framework to…

Dolls have accompanied children with a variety of activities, including the practice of reading. However, the current literature has neglected to provide empirical support that reading to dolls has influenced reading fluency or the child's belief in their reading ability, known as reader self-efficacy. This study sought to answer the questions of…

Spatial skills, the set of cognitive skills that are responsible for our understanding of objects in real and imagined spaces, have been identified as a potential gate-keeper for STEM success. Because of the recent emphasis on improving education to prepare for the increasing demand for workers in STEM fields, there is a rising interest in…

The "Pygmalion effect," is a construct that states that people often rise to the level that is expected of them (Chang, 2011). This is closely related to the "law of expectations," in which individuals receive what they expect to receive. These ideas may be applied to the educational arena when related to teacher perceptions…

Spatio-temporal processes are ubiquitous and prevalent across disciplines. Understanding the mechanisms underlying processes and integrating this information into models is of great interest, as it can improve forecasting accuracy and align with scientific motivation. Examples of such models include Partial Differential Equation (PDE) Models or…

Chapter 1 is a seismic study of the mantle structure of the passive margin of northeastern North America. This region experienced multiple episodes of rifting and orogenesis in the past, and the study aims to understand how the Wilson Cycle impacts the geometry of the upper mantle seismic structure beneath southern New England using Sp receiver…

In the modern era, Geographic Information Systems (GIS) have revolutionized diverse fields yet a deficiency in geographical education lingers in the U.S. educational system. This dissertation offers a thorough analysis of this gap, focusing on the potential of the GIS as an innovative solution for enriching geographical education. The Geospatial…

Science museums conduct presentations for their audiences to attract and educate visitors, yet research on presentations has primarily concentrated on whether individual presentations were effective. This mixed-methods, quasi-experimental study looks at how the presenter's mental and physical engagements within a presentation affects audience…

The present dissertation reports two experiments that examine implicit and explicit language learning methods and their impacts on early vocabulary, grammar, and phonological acquisition, in addition to working memory, proactive/reactive control, and fluid intelligence, as well as learner motivation. Experiment 1 investigated adult L2 acquisition…

Visual-spatial literacy is an essential component to developing STEM literacy, which is a primary focus of the three-dimensional Next Generation Science Standards (NGSS) framework for science education. Because scientific data is frequently communicated through visual representations, it is important for members of the current science and…

The landscape of undergraduate biology education has been shaped by decades of reform efforts calling for instruction to integrate core concepts and scientific skills as a means of helping students become proficient in the discipline. Assessments can be used to make inferences about how these reform efforts have translated into changes in…

The achievement gap between African American students is growing larger compared to other racial groups. Despite being cognizant of the alarming African American learning gap, there continues to be minimal research that explains and determines the impact of the classroom teacher. Moreover, as Black children continue to underperform on standardized…

Physics is known for its emphasis on innate brilliance as a prerequisite for disciplinary membership and success. Women, Black, Latine, and Indigenous individuals remain vastly underrepresented and marginalized in physics spaces, a reality that is due in part to oppressive stereotypes that position them as less inherently intelligent than their…

Chemistry is considered a difficult subject by most students. Its difficulty lies in Chemistry's complex and abstract nature. This highly abstract nature requires constant interplay and coordination between the macroscopic, particulate, and symbolic representations. Experts can successfully navigate the various representations without overloading…
